呃...想問樣唔知係咪叫"TAMP"既野...

請原諒新手問個小小問題
想搵部桌上AMP仔, 有RCA IN, OUT去無源喇叭度, 淘X 好似有好多,
如果想去淘X搵部加埋唔過五百既應該點揀/有無介紹??
THANK YOU

For me , I purchased Topping TP30 ( with USB to connect computer for music ) with RMB 498.

Class T amplifier
http://en.wikipedia.org/wiki/Class_T_amplifier

A Class T amplifier is an audio amplifier integrated circuit design. Rather than being a separate "class" of amplifier, Class T is a registered trademark for Tripath's amplifier technologies.

It is an implementation of Class D amplifiers, but is claimed to improve the control scheme to create more efficient and higher quality audio amplification. One of the amplifiers, the TA2020, was named one of the twenty-five chips that 'shook the world" by the IEEE Spectrum magazine.[1]

The control signals in Class T amplifiers may be computed using digital signal processing or fully analog techniques. Currently available implementations use a loop similar to a higher order Delta-Sigma (ΔΣ) (or sigma-delta) modulator, with an internal digital clock to control the sampled comparator. The two key aspects of this topology are that (1), feedback is taken directly from the switching node rather than the filtered output, and (2), the higher order loop provides much higher loop gain at high audio frequencies than would be possible in a conventional single pole amplifier.

Despite Tripath's claimed increased performance at a price similar to class D technology, financial difficulties caused Tripath to file for Chapter 11 bankruptcy protection on 8 February 2007.

As of 2012 the Tripath based amps are still very popular, especially amongst the DIY audio fraternity as they are cheap to buy, have a reputation for sounding very good, and are often easy to upgrade with better quality components.

    多謝師兄詳盡既解釋呀
咁我有部PRODIGI CUBE,
如果買左呢部野用唔用埋? (USB->CUBE->TP30)
定係直接USB->TP30?

Namhei

求解答, 因為prodigi可以好方便咁換opamp,
如果用埋可唔可以當係調音? (唔想"哂"左部野)
